Hey guys, I'm considering buying a used Alienware m17x r4 with a 660m for around ~1000- 1100, then selling the 660m for around $200 and buying a 680m for around $400-500 and using it until the 780m gets a little cheaper. I have a few questions.. How long can I expect to run games on this setup on ultra/high/medium? Whats the best cpu I can fit in this model? How many hard drive slots does it have? Is there something better I can get for the money that will last longer? Is the bios unlocked for overclocking? Should I get something that can use the new haswell cpus? From what I've read the biggest advantage of haswell is longer battery life, but I'm not concerned about that at all since I will have it plugged in 99% of the time. I'm looking for something that has a lot of power and is very upgradable/moddable. I know the next gen consoles are right around the corner and I'd hate to buy a laptop that will be rendered useless fairly fast from the graphics leap. I know desktops are cheaper and better, but unfortunately those aren't an option since the only internet options I have at home are satellite and dial up and I have to go to a friend's house to do any online gaming. Thanks.
